Battery-grade Nickel Foil
Targray supplies battery-grade nickel foils designed for use as current collectors in next-generation lithium-ion and solid-state batteries. Engineered for superior conductivity, mechanical stability, and corrosion resistance, our nickel foils enable battery manufacturers to improve energy density, power performance, and thermal reliability across cell formats and chemistries.
Nickel Foils for Lithium-ion Batteries
Offered in a broad range of thicknesses, our battery Nickel foil is used in a variety of rechargeable battery applications including cellphones, laptops and retail electronics, as well as higher-level applications such as supercapacitors.
Electrodeposited (ED) Nickel Foil
Targray’s nickel foils are manufactured to meet the stringent performance, purity, and dimensional tolerances demanded by EV, ESS, and consumer electronics applications.
Key Characteristics
- Uniform thickness and flat surface
- Wider and thinner than rolled nickel foil
- The product is oil-free; No need to clean/rinse before use
- Excellent mechanical properties, acid and heat resistance, and etching ability
Surface Treatments Available
- Electro-degreasing and roughening for improved coating adhesion
- Carbon, oxide, or polymer coatings for enhanced interface stability
- Double-side treated foils for bipolar electrode designs
Product Advantages
- Enhanced Conductivity and Corrosion Resistance
Nickel’s high electrical conductivity and passivated surface reduce resistance growth during cycling, improving overall power output.
- High-Temperature and Chemical Stability
Nickel foils maintain mechanical and chemical integrity in aggressive electrolyte or high-temperature environments, making it ideal for next-generation cathodes and high-voltage chemistries.
- Dimensional Precision and Uniformity
Tight control of thickness and surface finish ensures consistent coating, calendaring, and adhesion performance in high-speed production lines.
- Compatibility Across Chemistries
Optimized for LMFP, NMC, LCO, and solid-state battery platforms. Nickel foils can also be surface-treated to enhance adhesion with carbon or polymer-based coatings.
Key Applications
- Lithium-ion batteries for electronic devices, EVs and supercapacitors
- Electromagnetic (EMI) shielding devices
- Thermal sensors
- Printed Circuit Boards (PCBs)
Applications in Battery Design
- Anode Current Collector in lithium-ion and lithium-metal cells where aluminum is unsuitable due to potential oxidation.
- Solid-State Batteries, where nickel provides strong electrochemical stability with Li metal and sulfide electrolytes.
- High-Power Cylindrical and Prismatic Cells, demanding excellent electrical and thermal conductivity.
- Fuel Cell and Hybrid Systems, as an oxidation-resistant conductor or catalyst support.
